In fairness, Foundations of Physics (where this paper by Meessen was published) isn't a trash journal, but it is an odd duck. The editor in chief is Nobel laureate Gerard 't Hooft, who everyone agrees is brilliant, and generally still rigorous strictly speaking, but whose interest have become much less mainstream. Articles published in the journal are rarely flawed in a technical sense, but they do often explore highly speculative avenues that are usually considered unpromising for good reason. I'd say there's a good analogy to cold fusion, which is a field that is highly unfashionable for good technical reasons, and which has attracted a lot of cranks, but in which there are still formally open problems and which can't be completely dismissed.
